How Many Amps Is 652 kW at 460V?

652 kilowatts at 460V works out to roughly 962.74 amps on AC three-phase at PF 0.85. That is typical for commercial HVAC, industrial motors, rooftop units, and three-phase panel loads. See the DC and alternate-phase numbers below for other circuit types.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 652 ÷ 460 = 652,000 ÷ 460 = 1,417.39 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

652,000 ÷ (0.85 × 460) = 652,000 ÷ 391 = 1,667.52 A

AC Three Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (√3 × PF × V_L-L), where V_L-L is the line-to-line voltage

652,000 ÷ (1.732 × 0.85 × 460) = 652,000 ÷ 677.21 = 962.74 A

Power Factor Reference (AC three-phase)

How the line current for 652 kW at 460V changes with load power factor, on the same AC three-phase circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

Load Type	PF	652 kW at 460V (AC three-phase)
Resistive (heaters, incandescent)	1	818.33 A
Fluorescent lamps	0.95	861.4 A
LED lighting	0.9	909.26 A
Synchronous motors	0.9	909.26 A
Typical mixed loads	0.85	962.74 A
Induction motors (full load)	0.8	1,022.91 A
Computers (without PFC)	0.65	1,258.97 A
Induction motors (no load)	0.35	2,338.09 A

AC Conversion Comparison

On DC, 652kW at 460V draws 1,417.39A. AC single-phase at PF 0.85 pulls 1,667.52A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 962.74A per line since the same 652kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	652,000 ÷ 460	1,417.39 A
AC Single Phase (PF 0.85)	652,000 ÷ (0.85 × 460)	1,667.52 A
AC Three Phase (PF 0.85)	652,000 ÷ (1.732 × 0.85 × 460)	962.74 A

Frequently Asked Questions

How many amps is 652 kW at 460V?expand_more

652 kW at 460V draws about 962.74 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 1,417.39A on DC, 1,667.52A on AC single-phase.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 652 kW is easier to express than 652,000W. The math is identical, just scaled by 1000.

How many amps does a 652 kW EV charger draw at 460V?expand_more

460V is commercial/industrial panel voltage, not a typical AC EVSE feed to a vehicle. On three-phase 460V, 652 kW works out to about 962.74A per line (three-phase at PF 0.85). In practice, 400-480V three-phase is usually the AC input to a DC fast charger (50-350 kW CCS/NACS stations like Tesla Superchargers), which rectifies to DC and delivers that directly to the vehicle, rather than an AC EVSE connector. A 652 kW figure at 460V is most likely the AC feed to a smaller commercial cabinet or the control-side input of a larger DC fast charger, not an at-the-car AC current.

What is 652 kW in watts?expand_more

652 kW equals 652,000 watts. Multiply kilowatts by 1000.

How much does 652 kW cost to run?expand_more

652 kW costs $110.84 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $26,601.60 per month.
